Retailers' Descriptions

The Black Diamond Lost Arrow Pitons are light enough that you may forget they're on your harness. But when you're in a thin-to-medium crack and need pin-worthy protection, these bad boys get the job done. Black Diamond crafted these out of hot forged steel to keep the weight down (#1 weighs two ounces) and the strength up. Each piton has a number so you can find the correct size during critical moments where you can't shuffle through all your gear.

The meat and potatoes of a nail up rack, Black Diamond Lost Arrows are tough enough to withstand repeated abuse - hot forged big wall pitons patterned after the original designs of John Salathe and are as light as possible for their given size.
